Reading parmetric sweep data through ocean

lahsivece

Hi All,

I have a set of parmetric sweep results generated through spectre simulation . These file names are of the format 

"sweep_variablename_-<iteration numbers>_sweep_another_variable_name-<iteration_number>_....tran.tran"

I am trying to read the file through Ocean and perform some analysis on data generated. My ocean script looks like following:

sprintf(rdir "<path_to_spectre_simulation_directory>/spectre/schematic")
openResults(strcat(rdir,"/psf")) 

; The above sets the results directory to the psf folder. All parametric sweep results are dumped there.

 

selectResult('tran)
clip_v1p=clip(v("/V1P" ?result "sweepb2_1-000_sweepb1_1-000_sweepb0_1-001_tran-tran") 010e-09 28e-09)

On executing the script  i get following error message

The output '/V1P' you selected does not exist.  Type
          outputs() to see the list of available outputs or type
          help('v) for more information on the 'v' command.


However when I execute outputs() I get the netname in the list.

What am I doing wrong ?

I can read single spectre simulation data through ocean but Can I read parametric sweep spectre simulation data through ocean ?

Please advise.

Thanks & regards

Vishal

    Hi Shawn,

     1) I have already opened the results directory using openResults command .

    2) I am not using paramRun command in my .scs file. Do I need to use it ? To do nested armetric analysis , I have modified my input .scs as  following

    sweepb2_1 sweep param=b2 values=[0.0] {
      sweepb1_1 sweep param=b1 values=[0.0 ] {
        sweepb0_1 sweep param=b0 values=[0.0 1.2] {
    tran tran stop=50n write="spectre.ic" writefinal="spectre.fc" \
        annotate=status maxiters=5
        }
      }
    }      

    This geneartes data at a single location when I execute netlist from command line. I would like to have seperate location for each sweep variable ouput run. (in ocean this is easy)

    Thanks & Regards
